Loosing brakes starts when moving backwards I have to put both feet on pedal to stop, then does same thing when moving forward. Doesn't do it all the time but you never know when its going to happen. Started at about 29000 miles have about 29500 on it now haven't driven in a few months

The contact owns a 2014 Chevrolet Silverado 1500. While driving 10 mph with the brake pedal depressed, the vehicle failed to come to a complete stop. As a result, the contact rear ended another vehicle. The air bags did not deploy. A police report was filed. There were no injuries sustained. The vehicle was not taken to a dealer or independent mechanic for diagnostic testing or repairs. The manufacturer was not made aware of the failure. The failure mileage was 80,000.

2014 Chevrolet Silverado multiple recalls on this vehicle and just received a letter about the faulty vacuum pump for the braking system. Been having issues with mine for over a year, but apparently it's only covered by the manufacturer if it's under 72K miles. Either it's a manufacturer fault or it's not. My being over 72K makes it 'my problem' I suppose. Sad they are allowed to get away with this.

Takata recall - tried parking today and backed into my parking garage wall at work - no damage to vehicle but scared me quite a lot to all the sudden lose complete control of my brakes - pedal became stiff - would barely move no matter how hard I pressed it and then brakes stopped working completely. All the forums I am reading is related to vacuum pump. This is a joke that this hasn't been recalled yet. These geniuses are waiting for someone to get killed before they are going to fix it apparently. Truck is 2014 Silverado 1500 ltz Z71 with only 29,000 miles on it. Sure as hell is just out of warranty period.

Suspension makes noises when turning or going over bump. Driver seat feels like it moves/shifts slightly when making a turn. No brake pedal or 'rock' hard brake pedal at low speeds, in traffic, or when in reverse.

- Ft Stewart, GA, USA

Brakes became hard to push and truck wouldn't stop. It started off when backing into a parking spot and then driving forward slowly. That was last fall. Now the brakes are hard to depress all the time, and sometimes have to use both feet. Brought it to mechanic shop and it is the brake vacuum pump.

I lose power brakes while driving especially at slow speeds the pedal gets very stiff to where I can almost not even stop. It even started getting worse at high speeds now

- Charles City, VA, USA

While driving downhill on a local highway, another vehicle changed lane into my lane which forced me to brake to avoid a collision, but brake pedal was very stiff and required more force than usual to apply the the brakes. Fortunately, I did not hit the other vehicle and but had to pull over to a parking lot check on my family who were shaken up about the ordeal. I turned off the vehicle for a few minutes to see if it resets the problem but after starting the vehicle and driving it around the parking lot a few times, the problem was still there and a brake assist service message was now showing.

- Mangilao, GU, USA

Brakes became hard to push down and could barely stop. Luckily I was backing into a parking space at work and the sidewalk ledge stopped me. Now when I try to stop the brakes will only push down about an inch then are almost impossible to push down to stop. From what I read online the problem is likely the vacuum pump.

- Fort Mill, SC, USA

The contact owns a 2014 Chevrolet Silverado 1500. While driving approximately 35 mph, the brake pedal was depressed, but failed to stop the vehicle. The contact stated that the brake pedal was very firm. Approximately ten minutes after the failure, the service brake assist warning indicator illuminated. The vehicle was not diagnosed or repaired. A dealer was not contacted; however, the manufacturer was made aware of the failure. The approximate failure mileage was 79,000.

Brakes engaged and locked up while driving during normal road conditions in July 2018.towed to dealership & problem was the braking module. However, 6 months later and the brakes engaged and lock up again while driving on normal road conditions. Towed to dealership & this time they determined the booster valve controlling the brake fluid was the issue. 2 days later, the brake assist engaged while driving and the brakes locked up again. Had to depress the brake assist button multiple times to get it to release. These instances are occurring while road conditions are bare & temps are above freezing. This is dangerous since brakes lock up while in the middle of traffic traveling anywhere from 30 mph to 50 mph.

When trying to stop at low speeds the brakes act like loss of power brake and have at least 5 times almost hit a car in front of me because couldn't stop. I took it to the local GM dealer and had it repaired and it was the vacuum pump, and after finding out the problem I found on the web that there is a big problem with this on 2014-2018 GM trucks and was advised to file a complaint because it is a huge problem and should be recalled, especially after it cost me over $800. I have around 72,000 miles and looking on the web quite a few have had this problem as early as 10,000-30,000 but was taken care of under warranty and probably weren't reported

At low speeds, the brake pedal becomes hard/impossible to press and does not slow down the truck. It feels as if I have no control over stopping the vehicle. This seems to be happening to a lot of owners of these trucks according to what I am seeing while researching the issue.

- Moncks Corner, SC, USA

At low idle the brake assist does not work. I have to push very hard on the brake to stop. In city stop and go traffic it's impossible

- Jonesboro, GA, USA

At low speeds or idle, power brakes are lost requiring to use emergency braking to prevent collisions.

- Landisburg, PA, USA

Brake pedal becomes hard after pressing 2 or 3 times when engine is at or near idle resulting in absolutely zero braking ability. Occurs in both forward and reverse. Resulted in having to use the emergency brake in order to prevent a collision.

- Baudette, MN, USA

Silverado will loss braking power at low speeds (10mph<) and condition worsen when under stop-and-go-traffic.I have determined the problem to be related to the vacuum pump - 12669488 GM original equipment vacuum pump

- Davenport, IA, USA

Replaced the brake booster twice in 24 months. Both times the situation was the same, I was driving as usual and in normal traffic when I needed to brake but my pedal was hard as a rock and I had to use both feet to brake.

- Mt.Vernon, TX, USA

The brakes keep going out like there is a vacuum problem. The pedal will go all the way down to the floor and barely can stop. Happens in reverse and forward. Nothing comes up on the dash as anything wrong. Have to pump the brakes and then it goes all the way to the floor. Happens coming up to stop signs and when backing into a parking stall.

- Milton, WI, USA

At slow speed braking such as entering a parking spot both forward and reverse and slow speed braking as in stop and go traffic the brakes seem to stop working and the pedal gets hard to depress. Stopping occurs when great foot pressure is applied and maintained. Even then it will creep forward or backward a few inches
